European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 2937-2946

Background
Chronic Kidney Disease (CKD) is recognized as a major medical problem
worldwide. Electrocardiogram (ECG) remains an essential tool despite the development of
modern technologies, for evaluation of cardiovascular disease.
Aim
To study the electrocardiographic findings along with the associations with the laboratory
variables and prevalence of cardiac arrhythmias in patients of chronic kidney disease
undergoing haemodialysis.
Method
The study was conducted on 100 in-patients who were undergoing Haemodialysis in G.R.
Medical College, Gwalior. A standard 12 lead ECG was obtained just before and after the
haemodialysis procedure. The electrocardiograms was reviewed on descriptive reports of
variables: Rhythm, Heart rate , P wave abnormalities, LVH, QT interval/ QTc, ST segment
changes. Patient was placed on the Holter monitor for 24 hours just an hour before the
dialysis.
Result
In the study subjects , there were 51% of them who had serum creatinine of (5.1-10mg/dL)
and 2% had serum creatinine of ( > 20 mg/dL). There were 37% of the study subjects who
were Smoking and 27% of them were Alcoholics, 81% were Hypertensives , 19% were
having Diabetes Mellitus and 14 % were Obese. It was observed that 5% of the subjects
showed Atrial Fibrillation on ECG after Dialysis and 95% of them showed a Sinus
Rhythm. Changes in the ST segment and Tall T wave on ECG were observed in 25% and
35% of the study subjects. Supraventricular Ectopic findings were observed in 19% before
dialysis and 48% during dialysis and 15% after dialysis respectively. On ECHO, 60% of
subjects showed Left Ventricle Hypertrophy and 28% had Diastolic dysfunction.

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 2055-2064

Background:Snake bite is an occupational hazard for farmers and farm laborers in the Indian
subcontinent. Every year approximately 15,000 people reportedly died due to snake venom
interaction in India alone. However, unreported deaths are estimated to be many times greater
than the reported cases in the subcontinent.
Materials & Methods:ThisCross Sectional Observational Study was carried on sample size of
75 patients of snake bite admitted in Ward/ICU, Department Of Medicine, NSCB Medical
College, and Jabalpur on patients of snake bite reporting from all over mahakaushal area of
central India from March 2017 to August 2018.
Results: CPK-MB analysis shown to have highest raised values in neurotoxic group that is
32.3±0.9 IU/L which was higher in cases where local signs were prominent, 34.0±1.1 IU/L and
in cases without local signs it was lower 30.7±1.6 IU/L. CPK-MB values were for vasculotoxic
bites was also raised 27.3±1.2 IU/L, while for non-poisonous snake bites it was below upper
limit, 21±2.1 IU/L. A total of 39.2% (n=33) patients shown to have positive ECG findings while
rest 60.7% (n=51) shown no abnormality in electrocardiogram. Analysis of 2D-ECHO findings
was done for pattern of positive findings and found that most common positive finding was
pericardial effusion with 9 (10.71%) patients followed by 6 (7.1%) patients showed diastolic
dysfunction, and 5 (5.9%) patients each shown to have systolic dysfunction and RWMA.
Conclusion: CPK-MBanalysis shown to have highest raised values in neurotoxic group which
was higher in cases where local signs were prominent, and in cases without local signs it was
lower. Abnormal ECG was significant predictor of mortality in vasculotoxic snake bites.
Echocardiography was a significant predictor of mortality in neurotoxic bites.

The prevalence of cardiac autonomic neuropathy (CAN) in type 2 DM patients increases with
the duration and poor glycemic control. Patients with CAN are at increased risk for
autonomic dysfunction like resting tachycardia,abnormal systolic and diastolic function
leading to syncope and dizziness, prolonged QT interval, silent ischemia/infarction, lethal
arrhythmias and sudden death.Usage of 5 simple and cheap bed side tests for autonomic
function and corrected QT interval from ECG are helpful in early diagnosis of CAN. Early
recognition of CAN is helpful in delaying effects of CAN by strict control of blood sugar and
following healthy life style. Our study was conducted on100known and newly diagnosedType
2 Diabetes Mellitus patients<60 years whopresentedto Medicine OPD and admitted in IPD
wardsin Maharani LaxmiBai Medical College.Out of total 100 patients,49% had normal
score(0,1); 25% had borderline score(2,3,4); rest 26% had abnormal score ≥5; the prevalence
of CAN was 51%.Among 100 patients 47% patients were foundwith poor glycemic control
(HbA1C ≥ 8),in these 17% had early and 21% had definite CAN. Out of 100 patients of the
study, 55% patients had QTc>440ms out of which 17% had early and 23% had definite CAN.
The CAN also increased with older age group. So it is important to diagnose CAN early in
asymptomatic diabetics. There is significant correlation between CAN and QT prolongation.
QT interval in ECG can be used to diagnose CAN with reasonable sensitivity and specificity.
Usage of 5 bedside autonomic function tests are very helpful in early diagnosis of CAN.Strict
control of blood sugar can delay the early development of CAN. Intensive control of blood
sugar can delay the early development of CAN.

Non-invasive cardiac examination in standard clinic is still using 12-lead electrocardiograph. The results of the examination are presented on ECG paper or on the monitor screen. A normal electrocardiogram on one lead is not necessarily normal for the other lead, because each lead represents a certain part of the heart so that one by one is necessary. This examination takes time so that it can increase the stage of the disease if the patient turns out to be in an abnormal condition. This paper aims to correlate the peak amplitude of each lead to normal and abnormal heart conditions. If it is known that the peak amplitude is correlated between the leads, the other leads do not need to be checked, so that the diagnosis time will be obtained faster. Cardiac biosignal data that has been sampled with a frequency of 250 Hz is a discrete signal that can be stored digitally in a database. 10 samples of normal conditions and 10 samples of abnormal conditions were analyzed using Saphiro-Wilk so that the data were normally distributed. Spearman correlation analysis is used to get peak amplitude correlation between leads. The results showed that for abnormal conditions with a significance of 0.01 there was a correlation between the peak P lead I with leads III and V5, while for normal conditions there was a correlation between peak P lead I and leads V3 and V4. In abnormal conditions there is a correlation between peak R lead II and V6, while in normal conditions there is a correlation between peak R lead I and aVF.

Background: Hyperthyroidism is defined as excess concentration of thyroid hormones
in the body due to either increased synthesis of the thyroid hormone, increased release
of preformed thyroid hormones, or from endogenous or exogenous extrathyroidal
sources. The present study was conducted to assess cardiovascular manifestations of
hyperthyroid disorder patients.
Materials & Methods: 104 patients of hyperthyroidism of both gendersunderwent
clinical evaluation, basic laboratory tests like CBC, RFT, LFT and ECG and 2D ECHO
were performed in these patients to evaluate the presence of any cardiac manifestations.
Results: There were 34 males and 70 females. Age group upto 40 years had 20, 41-60
years had 34 and >61 years had 50 patients. Common symptoms were pallor in 90,
edema in 86, moist skin in 74 and eye signs in 53. Cardiovascular symptoms recorded
were chest pain in 82, palpitations in 95 and breathlessness in 60. Among 104 patients,
ECG changes were seen in 42 patients. Out of this, sinus tachycardia was seen in 65%,
AF in 10%, ST T changes in 6%, RVH in 7%, LVH in 11% and RBBB in 5%. The
difference was significant (P< 0.05).
Conclusion: Cardiovascular manifestations are quite common in hyperthyroid patients.

European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 2, Pages 1962-1966

Background: Microalbuminuria has been recently found to be a marker of
atherogenesis. It is associated with various risk factors of atherogenesis and damage of the
vascular endothelium. There have been few studies in which it has been found that
mortality in cardiovascular disease are increased with microalbuminuria. Urine is
collected over 24 hours and this study has similar sensitivity as urinary albumin creatinine
ratio. A urinary albumin to creatinine ratio is as sensitive as a 24 hours urine study even
though it itself is a gold standard test. In patients with CAD other factors have been
explored then urinary albumin has been recently identified.
Objectives: To assess correlation between urinary albumin creatinine ratio with coronary
artery disease and to correlate Urinary albumin creatinine ratio (UACR) with
Framingham heart study Cardiovascular disease (FHS-CVD) score in all patients of
coronary artery disease.
Methodology: In this study which is cross sectional, Subjects to be included in the study
will be explained regarding the study and proper consent will be obtained. A random urine
sample will be collected. Urinary albumin concentration will be measured by auto analyser
and urine albumin creatinine ratio will be calculated. The values of the same will be
recorded and will be statistically analysed.

The Electro Cardio Gram (ECG) is a parametric index to diagnose heart diseases. During the process of acquisition of the ECG signals, it is added up by large amount of noise, which affects the patient diagnosis with respect to telemedicine. The noisy ECG signals have drift in baseline, motion electrodes artefacts, interference of line, muscle contraction noise, etc. Noise reduction is accomplished by making using of adaptive filter which employs wavelet transform. Computer simulation results are shown for the improvement in performance. This methodology adapted successfully removes various types of noise with Signal to noise ratio (SNR). The impact of noise and removal of it are shown in the waveforms and the methodology adopted has produced 82% improvement on the SNR of de-noised signals.
